Subject [jira] [Commented] (OPENJPA-2337) ClassFileTransformer modifies bytecode
Date Wed, 20 Feb 2013 22:59:12 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13582628#comment-13582628
] 

Kevin Sutter commented on OPENJPA-2337:
---------------------------------------

But, if you got that far into ManagedClassSubclasser, then you must have openjpa.RuntimeUnhancedClasses
set to Supported or Warn, and that is not a recommended practice [1].

> When using the JPA ClassFileTransformer from a javaagent the expected workflow is to
simply convert in memory original class byte[] to an enhanced byte[].
> However since the code is shared with ant task, mvn plugin and main() enhancer it also
updates the file physically.
> That's a pain for load time weaving.
> Could it be skipped when using the ClassFileTransformer?
> sounds like a bug for me, wdyt?
